by kasperenok
Kashub is a Fabric game mechanics mod that adds a scripting layer and a built-in code editor for automating tasks in Minecraft.
What it does
Scripts are written in KHScript, a language with Lua and JavaScript-inspired syntax, and run inside the game. The editor opens with the K key and covers syntax highlighting, auto-completion on Ctrl+Space, more than 40 high-level commands, and debugging tools, so no external editor is needed for common work. The author lists automation of farms, building and grinding as the target tasks.
The mod is built with server owners in mind. A server operator sets the amount of automation permitted on a server, and can switch it off completely, while single-player and private worlds keep full access. Kashub is client required and server optional, so a server can run without it. It is released under the MIT License and is open source; the source code, issue tracker and wiki are public.
Files are published for Fabric only, for Minecraft 1.21.1. The latest build is v0.9.0-beta, released on 2026-01-25 on the beta channel, after a first release on 2025-12-14.
